Delicatessen king and big spender-Casanova Hans-Georg Fischer floats dead in his pool, apparently with a fatal cocaine OD, actually laced with lethal rat poison strychnine. Dr. Wendelin Winter must assess unwilling fresh widow Witwe Regine's mental condition. Cynical hedonist Fischer openly cheated on his wife, who keeps the business floating, and was equally gross to latest mistress Ariane Jäger, who nearly bumped into Wendelin's car fleeing from the pool on the fatal day, and has a jealous ex, emergency doctor Dr. Lohmeyer. Vegetables grocer Karl Baumgartner hated Fischer and concocted with gay florist Bernd Zeisinger, who spoils his gorgeous but unfaithful assistant Nicky Huber with the proceeds of a toxic side business. Gutter reporter Jacki Gosser took pictures of the adulterer in action and wants the intern; Winter's daughter Alexandra, to elaborate the boulevard scandal. An attempt on Zeisinger's life helps Winter complete the puzzle of crimes.
